Rentech voluntarily self-disclosed to EPA potential regulation violations in September 2008. In a related action, Rentech agreed to an EPA administrative order to replace within a year the leaking refrigeration unit with a unit that uses a nonozone depleting substance.
Chlorofluorocarbon refrigerants and certain substitute refrigerants deplete the stratospheric, or “good,” ozone layer allowing dangerous amounts of cancer-causing ultraviolet rays from the sun to strike the earth. Production of some of these chemicals was stopped in 1995, and federal law strictly controls their use and handling.
